We propose a neural-enhanced modulation scheme based on conditional GAN (cGAN) that leverages indoor multipath effects as a natural beamformer, enabling spatial selective transmission on low-end single-antenna IoT devices for the first time. The system is deployed end-to-end on Raspberry Pi, achieving signal coverage precision of 0.04 m²–0.5 m² (customizable) with 40%+ BER reduction in unintended areas.
